Fire Horizon - FIRE Portfolio Tracker & Retirement Planner

Hey Product Hunt 👋 I'm Logan, one of the two people behind Fire Horizon. This started in 2023 as a personal spreadsheet. I was deep into FIRE — reading everything, tracking my own numbers by hand — and I kept hitting the same wall: retirement calculators give you a single number and forget about you the moment you close the tab, and portfolio trackers have no idea what "Coast FIRE" or "Barista FIRE" even mean. I wanted one thing that actually understood the plan I was trying to build, not a generic retirement age. So the spreadsheet grew. Eventually I brought my friend Baylor on as co-founder, and what was a personal tool turned into something we thought the whole FIRE community deserved to have — because as far as we can tell, nothing else out there is both FIRE-native and a real portfolio tracker at the same time. That's Fire Horizon: link your actual accounts (or just import a CSV), and it tracks Coast, Barista, Lean, or Fat FIRE against your real holdings — not a hypothetical. Every formula we use is published and auditable, because a tool that tells you when you can stop working should be willing to show its work. It's been years of nights and weekends to get here, and this is genuinely our first time putting it in front of people outside the FIRE communities we grew up in. I'll be in the comments all day — tell me what's missing, what's confusing, what you'd want it to do that it doesn't yet. That feedback is exactly why we're here. Thanks for taking a look. — Logan
